. This invention is a non-glare reflector particularly adapted to the headlights of automotive vehicles, and is intended to suitably break up or deflect the direct rays from the headlight which cause'the blinding glare so prevalent in the usual headlight, without the interposition of special lenses which are now used to minimize the glare. 4 The main object of this invention therefore is to provide a non-glare reflector, one which will properly break up the rays which cause the glare common with ordinary r'eflectors.

Another object of the invention is to provide a non-glare reflector which is easily and cheaply constructed and requires no additional parts for the purpose of obviating the usual glare of the headlight.

Other objects and advantages of the invention will become apparent as the following description is read on'the drawing forming a part of this specification and in which similar reference characters are used to indicate similar parts throughout the-several views of which i Fig. 1 is a front elevation of the invention; ig. 2 is a sectional elevation through the focal center of the non-glare means; Fig. 3 is a section taken on line 3-3 of Fig. 2.

Fig. 4 is a diagrammatic view indicating the function of'the non-glare means.

The invention consists of the usual parabolic reflector 10, which is provided with the 5 usual flange 11 for mounting, and a lamp socket 12, all of which are of standard construction and thereforegrequire no descrip-- tion of form or functio The parts as described so far do not form a part of the invention, which consists in forming diametrically opposed insets 13 and 1 1 which are formed substantially as shown in Fig. 3, being of substantially V form and suitably rounded at the vertex as indicated at 15 and at the base as indicated at 16, a plan view showing the base to be substantially elliptical in form, and the ridge 15 forms a substantially straight line from the periphery of the reflector to the lamp socket, as shown 0 in Fig. 2. This operation-of insetting may be performed before or after forming of the standard reflector, and may be performed on existing reflectors which is a feature having considerable merit.

Fig. 4 indicates the function of these insets.- The rayswhich cause the usual glare are reflected from the upper and lower portions of the reflector, which portions are included in the insets shown in ,Fig. 1. Rays of light from lamp 17 striking on the exact center 18 of the inset are directed straight ahead while any rays 19 or 20 strike the sides of the inset and are either dispersed or directed to the normal part of the reflector where they are again changed in direction.

Therefore substantially all of the rays adapted to cause glare are broke upand dispersed, the reflector retaining substantially full efliciency without the attendant glare. The reflector may be substituted for any standard reflector of the same size so that no changes are required in the housing or other elements of standard lamps.

Having described an operative device it I will be noted that variations in construction 7 and arrangement, or form which are consistent with the appended claims may be resorted to without detracting from the spirit or scope of the invention orsacrificing any of the advantages thereof.

I claim:

1. A reflector comprising a main reflector element of substantially parabolic form and having a lamp mountingsocket positioned at the focal axis thereof, a light deflector element above-said socket and a second light defleeting element below said socket, each -of said light deflecting elements consisting of a single straight ridge connecting the periphery of the socket and the peripheryvof the re flector and being disposed in a vertical plane relative to the focal axis, said deflecting elements having plane inclined sides and each intersecting the parabolic surface in a curve having an ovate form.

2. A reflector comprising a main reflector element of substantially parabolic form and having a lamp mountingsocket positioned at the focal axis thereof, a light deflector element above said socket and a second light deflector element below said socket, each of said light deflecting elements consisting of a single straight ridge connectin of the socket and the perip the periphery ery of the re- 5 flector and being disposed in a plane perpendicular to the focal axis, s

aid deflecting ele ments each being V-shaped in transverse cross-section and mtersectmg the parabolic surface in a curve havmg an ovate form.
